MAX40203AUK+T Description

Short technical summary and product information.

The MAX40203AUK+T is an ideal diode current switch designed for low-voltage, portable electronic devices. It operates from a supply voltage range of 1.2V to 5.5V and provides a significantly lower forward voltage drop compared to Schottky diodes, typically 90mV at 1A.

 

This device features a current limit of 2A during short-circuit or fast power-up events and includes thermal protection. When disabled, it can block voltages up to 6V in either direction. The MAX40203AUK+T is available in a compact SOT-23-5 package, making it suitable for space-constrained applications.

 

Key electrical characteristics include a low supply quiescent current of 300nA (typical) and a reverse-biased leakage current of 10nA (typical). It is specified for an operating temperature range of -40°C to +125°C.

 

Applications include notebook and tablet computers, battery backup systems, cellular phones, and USB-powered peripherals.
